It is probably good for you to have had learned the lesson relatively early, even though you took some losses with your shitcoin involvement.
Historically, there have been a lot of folks that get distracted into shitcoins, and surely some of them learn their lesson and they begin to focus more on (or maybe completely on) bitcoin. Shitcoins will continue to be distracting, which justifies part of my suggestion to make sure to limit shitcoin involvement to no more than 10% of your bitcoin holdings, and try not to cheat in regards to your ways of structuring such shitcoin involvement in the event that you cannot resist shitcoins. I am not even recommending involvement in shitcoins at all, yet I am suggesting if guys cannot resist getting involved in shitcoins, then to limit their involvement to no more than 10% of the size of their bitcoin involvement, which will at least limit the damage and allow them to mostly stay focused on the prize (namely bitcoin), and sure, if they happen to find some shitcoins that outperform bitcoin in the short or long term, then I don't have any problem accepting those sorts of happenings if they were miraculously able to identify such outperforming shitcoins.
You are right sir, I have realized the importance of Bitcoin by going to Shitcoin. I think it would have been better if I had bought Bitcoin instead of Shitcoin. And Shitcoin always has to be worried. Now I am not afraid anymore, I can sleep peacefully. I regret that I invested in Shitcoin even after selling Bitcoin. But anyway, I survived just a little. Yes, you said that more than 10 percent should not be involved in Shitcoin, but I think this 10% can be invested in Ethereum. And it is difficult to find such Shitcoin that will surpass Bitcoin. We may lose many dollars by falling into this trap. Greed works more in Shitcoin. There is no Shitcoin as reliable as Bitcoin, with such volume, market cap and popularity. Many people have gone bankrupt by investing in Shitcoin. So if someone asks for advice, I always advise them to buy Bitcoin.
